IMPROVEMENT IN SULKipLQl/VSn Specification forming part of LettersPatent N o. 188,797, dated March 27, 1877 application led February 8,1877.

To all whom it may concern Be it known that I, OREN DELORMA HALL, ofFreeport, in the county of Stephenson and State of Illinois, haveinvented certain new and useful Improvements in J ointe'd or Hinged BeamSulky-Plows, and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure l represents a side elevation ot the machine. Fig. 2 is a topfront view, showing the construction ot the draw-rod. Fig. 3 is asectional View of the box, showing draw-rod,

chain and pulley, and latch in poslt-ion to hold the draw-rod when theteam is plowing'. Fig. 4 is a front elevation, showing the machine inoperation, with the carriage adjusted so as to rectify the unequalelevation ot' the wheels.

My invention relates, irst, to the mechanism under the control of theoperator, whereby the plow may be raised up by the power of the team; orit may be raised or lowered at will by means of a lever moved by thehand or foot of the operator.

It further relates to the mechanical contrivance moved by the feet ot'the operator, by which the power ofthe team may be instantly applied tothe raising ot' the plow without the backing or stopping the team.

In Fig. l, B G is the plow-beam, pivoted at the point B, to which theplow D is attached by the standard It. K represents the seat for theoperator. Gr G is a chain and drawrod fastened to the lever F, andrunning under the pulley V and through the boxed beam A, terminating inthe ring H, to which the team is to be attached. p is a latch or triggerf1tted to notches in the draw-rod, and worked by the feet of theoperator to fasten and hold the draw-rod in place, either when 1t isdrawn out to raise the plow ofi' the ground, as represented by thedotted lines in Fig. l, as when going to and returning from the Ield, orwhen it is drawn back into position for plowing.

To raise the plow by the power of the team, the latch must be raised,when the power of the team will pull out the drawrod, and, by means ofthe lever F, raise the plow o the ground, as indicated by thedottedlines in Fig. 1; or, if the operator prefers, he may, withoutraising the latch, raise or lower the plow by means ot' the lever I,which is a branch of the lever F; or he may raise the latch., and thenuse the lever I in aid ofthe power of the team to raise or lower theplow.

L L are two levers, fastened one on each side of the trarne of thecarriage, to which cogged segments are attached, operating upon anupright notched rack, M, on either side, which rests upon and is tirmlyfastened to the axle of the wheels.

By means ot' these levers operating the segments, the frame ot' thecarriage may be raised or lowered at will.

Having thus described my invention, what I claim is- 1. The latch ortrigger p, adapted to be operated bythe feet, in combination with thedraw-rod and chain G G, for applying the power ot' the team'to theraising of the plow, and for holding the plow oft the ground,substantiallyr as described and represented. Y

2. ln combination with the draw-rod and pulley, the branch lever I, forthe purposes substantially as described and represented.

3. The combination of the draw-rod, pulley, and chain with the lever F,latch p, and plowbeam C, substantially as and for the purpose describedand represented.

In testimony'that I claim the foregoing' as my own I affix my signaturein presence of two witnesses.

OBEN DELORMA HALL.
